19 Claims.

This invention relates tol improvements in closures for bottles, jarsand like containers, and more particularly to closure seals which, whenonce broken or ruptured, can not be resealed or matched except in areadily obvious manner.

Among the objects of the invention may be noted the provision of aclosure seal for bottles, jars and like containers characterized byfeatures of improved construction and design; the provision of a closureseal of the above character which will assure the purchaser of thecontainer that the original contents thereof have not been tampered withor removed; the provisionof a closure seal for bottles and likecontainerswhich offers a high degree of 'protection to the purchaserthereof, in that the condition vof the seal will be indicative Vof theoriginality of the contents of the container; the provision of a closureseal for bottles, jars and like containers which is simple andinexpensive in construction and design, yet effective and efcient infunctioning; the provision of a closure seal for bottles, jars and likecontainers which may be applied to such containers without substantialmodification thereof, and which thus permits the use of bottles and likecontainers of conventional shape and design; and the provision of aclosure seal as above set forth which is Well adapted to fulfill theends for which it is intended.

Other objects will be in part obvious from the annexed drawing and inpart indicated from the following analysis of the invention, in whichreference is made to the accompanying drawing illustrative of one ormore embodiments of my idea, in which- Fig. 1 is an elevation, partly insection, of the closure seal in accordance with the present invention;Fig. 2 is an exploded detail of the sealing cap 40 and locking ringillustrated in assembled relation in Fig. 1;

Fig. 3 is a part section illustrative of a modified form of seal;

Fig. 4 is a part section of my improved closure 45 seal as used onbottles having a stopper type of closure;

Fig. 5 is a part section of a modified form of seal as applied to astopper type closure; and u Fig. 6 is a detail of the sealing band asillus- 50 trated in Fig. 5. l

While the closure seal of the present invention is applicable tocontainers generally, the illustrated form thereof and the followingdescription will indicate its application to bottles such as are used tomerchandise spiritous liquors,

wines, medicines, and generally goods of the class Where it is necessaryor desirable that the purchaser receive the original contents intendedto be purchased. It will be understood, however, that the seal isequally effective as applied to jar closures and to container closuresgenerally whether the container be of glass, metal or compositionmaterial and the application of the seal to be described to such latterform of containers is intended to be included within the scope of thepresent invention.

Referring to the drawing and particularly to Fig. 1, reference characterIIJ indicates a bottle having a neck portion II and a mouth portion I2adapted to be closed by a closure cap I3 of the screw type, such partsbeing conventional. Usually, such a bottle is formed with an exteriorboss providing an arcuate shoulder I4 extending about its neck portionand spaced from the open mouth slightly in excess of the lower edge of uthe screwkcap I3, whereby the cap may be screwed home and fully seatedwithout abutting against said shoulder I4.

According to the present invention, I provide the bottle neck portion IIwith an annular sealing pocket 20, such pocket being located generallyabout the shoulder I4 and extending therebeneath. The said pocket isformed in the bottle neck by certain apparatus and practices that arenot `a part of the present invention and need not be here described. Byreference to Fig. 1, it will be seen, however, that the pocket opensupwardly and that its inner wall is preferably formed by the outwardlyconvex surface of the shoulder I4 which overhangs the undercut outwardlyconcave continuation surface 2l thereof, although otherv arrangements ofoverhanging or shouldered surface might be utilized, as embodied inFigs. 4 and 5, for example.

The bottom wall 22 of the pocket 20 may extend relatively horizontallyand terminates at the pocket outer wall 23 which extends vertically fromthe bottom wall to the open mouth of the pocket. The said vertical Wall23 is defined by the inner wall of a guard flange 24 formed integrallywith the bottle neck I I and extending upwardly to about the upper lineof the neck boss or shoulder I4. The pocket so formed is thus providedwith a relatively wide entrance mouth, an intermediate restrictedportion, and a bottom portion of relatively greater width than saidrestricted portion, with the positioning of the shoulder I4 in relationto the vertical pocket wall 23 forming the restricted intermediateportion of the pocket.

The seal proper of the present invention includes a circular element 25which may constitute the skirt portion of a sealing cap 26, as in theFig. 1 construction, or may be in the nature of a band or sleeve, aswill be described hereinafter. In the Fig. 1 construction underconsideration, the skirt portion 25 is formed integral with the sealingcap 26 which is adapted to be placed over the screw closure cap I3, withthe skirt portion 25 extending into the sealing pocket 20 and havingformed along its lower edge a plurality of crimps 28. By reference toFigs. 1 andj2, it will be noted that the crimps 28 are directedoutwardly of the body of the skirt portion 25 and thus do not modify theinner circular surface of the skirt portion or of the cap 26 proper'.`The sealing cap 26 and particularly its skirt portion 25 integraltherewith is preferably fabricated of thin, resilient metal and may bespun `or pressed into its cup shape formation. Preferably the skirtportion is formed with a curved shoulder 30 disposed above the crimps 28and adapted to seat on the arcuate shoulder I4 of the bottle neck. Thearrangement and disposition of the skirt shoulder 3D in relation to thecircular top of the cap 26 and to the crimps 28 is such that as theskirt portion 25 of the sealing cap 26 is projected into the sealingpocket 2U, the shoulder 30 of the cap seats against the upper surface ofbottle neck boss or shoulder I4 prior to engagement between saidcircular top and the top surface of the closure cap I3, wherebytensioning of the cap 26 in the direction of its length is prevented,with the crimps 28 extending into the pocket 20 a depth suilicient toclear the restricted portion thereof as dened by the greatest diameterof the shoulder I4 of the bottle neck, and being disposed generally inthe bottom portion of the pocket of greater width.

With the sealing cap 26 so arranged, a locking ring 35, of exteriordiameter slightly less than the outer diameter of the pocket 2U, asdened by the wall pocket 23, is thereupon pressed into the pocket 20.The inner diameter of the locking ring 35 is such that as the lockingring moves into the pocket, the inner wall of the locking ring engagesthe outwardly directed surfaces of thecrimps 28 of the cap skirt 25 andbends or clinches'portions thereof, such as the dwells or valleys,inwardly around the lower curved portion of the shoulder I4, theresiliency of the metal of the skirt portion 25 causing the crimps toexert a spring reaction against the inner wall surface of the lockingring 35. Along the lower inner edge of the locking ring 35, I provide abead or abutment 36 which clears the boss I4 as the locking ring 35 ispushed into the pocket 20, but which of course engages the crimped edgeportion of the skirt 25. As the bead 36 moves past the crimped edge ofthe skirt, the springy nature of the skirt 25 causes its edge to expandand the high points of the crimps to seat in the corner formed by theinner vertical surface of the ring 35 and the upper portion of the bead36, thus t0 lock ring 35 within the .pocket 20.

It will be apparent that the sealing cap 26, due to its shoulder 3|]engaging on the upper surface of the neck boss I4 and with the crimps 28or portions thereof clinched around the under surface of said boss, isthereupon positively secured to the bottle neck, with the skirt portion25 of the cap also serving to lock permanently in the pocket the lockingring 35 in such manner that the ring prevents access to the 'lower edgeportion of the skirt 25 such as would be necessary to reor bentformation.

lease the crimps from their holding relation with respect to the neckboss or shoulder I4.

'I'he thickness and dimensioning of the various parts making up the sealas well as the dimensioning of the pocket 20 are such that the cap skirt25 has an interior diameter sufficient to clear the greatest exteriordiameter of the neck boss I4, thereby the cap 26 may be readily appliedin position Vto bef sealed. The thickness of the metal of the caprissuch'that the capv is selfsustaining and capable of holding its crimpedThe thickness of the ring 35, which may be formed from steel stock, issuch as to enable the ring to compress and forcibly bend inwardlyportions of the crimped edge 28 as pressure is exerted on the top edgeof the ring to force it into the pocket 20. The depth of the ring mayvary, as in some instances it may be desirable to have the ring hiddenfrom view Within the pocket 20 by the guard flange 26. Again, it may bedesirable to have the ring extend slightly above the top edge of saidguard flange as indicated in the constructions illustrated. The width ofthe pocket at its relatively restricted portion is such that the skirt25 may pass therethrough with sufcient clearance and also such as toprovide for the subsequent insertion of the locking ring 35, but notsufficient to permit, when the skirt 25 and locking ring are in lockedrelation, the insertion into the pocket of means designed to disturbsuch relation.

In order to provide a ready means of rupturing the seal, the material ofthe cap 26 may be scored as at 4U in the course of its manufacture,whereby the relatively upper portion of the cap 26 may be removed andaccess had to the screw closure cap I3. When the upper portion of thecap is removed, however, the lower skirt portion 25 thereof remainssealed within the pocket 20 by locking ring 35, and its relatively upperedge which may project Vabove the upper edge of the locking ring 35 willthereafter be visible. Since it is impossible to remove either the skirtportion 25 and/or the locking ring 35 from the pocket 20, their presencein the pocket is visible and lasting evidence that the seal has beenbroken. Any subsequent attempt to reseal the bottle as may be the casewhere the bottle is relled for the purpose of selling the substitutedcontents for the original will thus be readily discernible to thepurchaser of the refilled bottle.

It will be evident that any attempt to remove or melt down the skirtportion 25 in its locked arrangement in the pocket 2|] will resulteither in ready discernment or in breaking of the bottle. Sovalso, anyattempt to apply heat to the guard flange 24 for the purpose ofspreading it outwardly, whereby to remove the locked skirt portion 25and the locking ring 35, will result in breaking of the bottle neck.Accordingly, the above described arrangement is believed to offer simpleland efficient means for preventing the re-use and/or resealing ofbottles after the seal has been once broken.

Considering now the modified construction shown in Fig. 3, also adaptedfor sealing bottles utilizing screw cap closures, the arrangement ofbottle, bottle neck boss I4, pocket 20, and guard flange 24 is the sameas described in connection With the Fig. 1 construction as aforesaid.Instead of utilizing a sealing cap of stiff metal having an .integralskirt portion provided with crimps, however, the modified constructionmakes use of a frangible or readily breakable covering disposed over theclosure I3 and extending downwardly about the bottle neck. Such coveringmay be fabricated from metal foil and may take the form of a cap 26a,the lower skirt portion 2GbI of which extends downwardly into the pocket20, with its terminal edge extending below the shoulder I4 and into theenlarged bottom portion of the pocket. A circular sealingelement such asa band 25a provided with an inwardly curved top shoulder 36a, and withoutwardly directed crimps 28a along its bottom edge, is adapted to beplaced over the foil cap 26a and moved downwardly until its shoulder Mdengages on the upper surface of the neck boss or shoulder I4, with thelower crimped edge of the band extending into the pocket 20 and belowthe greatest diameter of the neck boss shoulder i4. 'Irhe curvedshoulder 30a of the locking band 25a. thus presses the skirt portion ofthe foil cap 26a` against the shoulder or neck boss M of the bottle. Alocking ring 35 having a lower and inner edge bead 36, as describedhereinbefore, is thereupon slipped over the bottle mouth and forceddownwardly into the pocket ill) and functions to force the crimps 28a orportions thereof inwardly to thus clinch the band 25a to the bottle neckboss. The locking ring 35 is locked within the pocket 2E) by thecoaction of the outer edges of the crimps 28a and the bead 36. It willtherefore be seen that by the aforesaid arrangement band 25a ispositively securedto the boss ll and acts to lock the ring 35 within thepocket 2t, while at the same time the skirt portion 2Gb of theV foil capis permanently secured against the neck boss I4. To open the bottle, thefoil of the cap 26a may be cut or torn and the top portion thereofremoved to .give access to the screw cap I3. The skirt portion 26h ofthe sealing cap is,`however, securely held to the boss lli, and cannotbe removed for replacement purposes nor can a new foil cap be applied.p. v

In Fig. 4 I have illustrated the same general form of sealing means forbottles provided with astopper type of closure. The mouth portion lZc ofthe bottle is closed by a'stopper such as a cork I3c which extends welldown into the bottle mouth. Where such bottle necks are not providedwith a shoulder such as the shoulder M described in connection with Fig.1, I may provide a shoulder effect by undercutting or reducing thethickness of the neck along reverse curvatures such as Mc, 2 le, suchcurved surfaces forming the inner wall of a sealing pocket 20c such asthe pocket 20 of the Fig. 1 construction, said pocketfbeing providedwith a bottom wall 22e and a vertically extending outside wall 23e denedby ,a guard flange 24e as described. A sealing cap 26C ofself-sustaining metal and of suflicient thickness `as to hold crimpsimparted to it, as will be understood from the Fig. 1 construction, isprovided with a lower skirt portion 25c formed with outwardly directedcrimps 28e, the cap being adapted to be placed over the bottle mouth,with its lower crimped edge extending into the pocket 20c, and thecrimps 28e being disposed slightly below the should-er Mc. The depth ofthe sealing cap in the embodiment under consideration is such that itscircular top bears on the edge of the bottle mouth and generally on thecork top, with the crimped bottom edge of the cap extending into thepocket. This arrangement makes unnecessary the shoulder 3D as in theFig. 1 construction. Upon the locking ring 35e being forced into thepocket, the said ring clinches the crimps 28e or portions thereofbeneath the shoulder Mc to hold the cap to the bottle mouth. Y Due toits resiliency, the metal skirt reacts on the ring 35e and with the beador abutment 36e of the ring as aforesaid to lock the ring and to preventits removal or that of the skirt portion 25e of the sealing cap.

The cap may be scored as .at 40o whereby the upper portion thereof maybe removed, with access then being had to the cork |30. As in thepreviously described construction, the skirt portion of the sealing capand the locking ring 35C are positively locked to each other within thepocket 20c and cannot be removed therefrom, except by breaking thebottle.

Considering now the embodiment illustrated in Figs. and 6, such isillustrative of a seal to be applied to bottles utilizing the stoppertype of closure as illustrated in Fig. 4, and including a sealing cap26d of foil or equivalent material such as is utilized in the Fig. 3construction. Such sealing cap has a skirt portion 26e which extendsbelow the curved shoulder Ille. A sealing band 2.562 is thereuponslipped over the foil cap 26d and moved downwardly into the pocket 20c.In order to define the position of the sealing band 25d within thepocket, the band is provided with downwardly extending legs 45 which maybe ribbed as at Mi to strengthen the same, and with the leg bottomsbeing adapted to rest on the bottom wall 22o of the pocket Zllc. Thelength of the legs is such that when the legs rest on said bottom wall22o the crimped portions 28d of the sealing band are disposed adjacentthe undercut shoulder Ille.

A locking ring35c similar to the locking ring of the Fig. 4 constructionis thereupon forced into the pocket 20c and acts to bend the crimps 28dor portions thereof inwardly and to clinch them about the undercutshoulder Mc, with the lockingring being thereupon locked by the coactionof the edge of the crimps with the bead or abutment 36o. As in the Fig.3 construction the metal foil cap 26d may be ripped or torn away topermit access to the cork 13e, but it will be understood that the skirtportion 26e of the foil cap is heldto the shoulder Hic within the pocket20c, and that the sealing band 25d and the locking ring 35e aremaintained positively in locked relation within the pocketc.

From the foregoing, it will be obvious that the present invention oilersa simple and efiicient means for sealing closures, such as used withbottles, jars, and like containers. While the seal may be readilybroken, the closure cannot be again resealed in the original manner, dueto the permanent locking of the locking ring in the sealing pocket, andthus the re-use and/or resealing of the bottle or container for thepurpose of `selling substituted contents for the original contents isrendered impossible or so difficult as to make the attempt at resealinghighly improbable and impracticable. Without further analysis theforegoing will so Vfully reveal the gist of this invention that otherscan by applying current knowledge readily adapt it for variousapplications wtihout omitting certain features that, from the standpointof the priorart, fairly constitute essential characteristics of thegeneric or specific aspects of this invention, and therefore suchadaptations should and are intended to be comprehended within themeaning and range of equivalency of the follow ing claims.
